Question

If tri ABC ~ tri PQR , AB =6.5 cm , PQ =10.4 cm and perimeter of tri ABC=60 cm , then find the perimeter of tri PQR ..... !

Answer 1

Solution:-
Given Δ ABC is similar to PQR 
So, perimeter of triangle ABC/perimeter of PQR = AB/PQ
(60/perimeter of Δ PQR) = 6.5/10
Perimeter of Δ PQR = (60 × 10)/6.5
Perimeter of Δ PQR = 600/6.5
Perimeter of Δ PQR = 92.307 cm
Or, 92 cm (rounded off)  Answer
 

Answer 2

Answer:

Given Δ ABC is similar to PQR 

So, perimeter of triangle ABC/perimeter of PQR = AB/PQ

(60/perimeter of Δ PQR) = 6.5/10

Perimeter of Δ PQR = (60 × 10)/6.5

Perimeter of Δ PQR = 600/6.5

Perimeter of Δ PQR = 92.307 cm
